2V0-21.23 Question 314
Select 2An administrator is troubleshooting a performance issue in a vSphere 8 environment. They need to identify a virtual machine with high CPU contention and determine if the host's memory resources are overcommitted. Which combination of vSphere resource monitoring tools should the administrator use to effectively diagnose the issue?
- A
vSphere Performance Charts
- B
esxtop
- C
vRealize Log Insight
- D
vSAN Health Service
- E
vSphere DRS Recommendations
Show answer and explanation
Correct answers: A, B
Explanation
To diagnose a performance issue involving CPU contention and memory overcommitment, the administrator needs tools that provide detailed and real-time resource monitoring. vSphere Performance Charts offer a graphical overview of resource usage, while esxtop provides in-depth, real-time insights into host and VM-level metrics. These tools complement each other for effective performance troubleshooting.
- A. Correct.
vSphere Performance Charts provide detailed metrics for CPU, memory, disk, and network usage at both the host and virtual machine levels, making it a crucial tool for identifying CPU contention and memory overcommitment.
- B. Correct.
esxtop is a powerful command-line utility that provides real-time resource usage statistics, including CPU contention, memory utilization, and other detailed host-level metrics, making it highly relevant for this scenario.
- C. Incorrect.
vRealize Log Insight is primarily used for log analysis and troubleshooting, but it does not provide real-time resource usage or performance metrics, so it is not suitable for diagnosing CPU contention or memory overcommitment.
- D. Incorrect.
vSAN Health Service is specific to vSAN environments and is used to monitor and troubleshoot vSAN-related issues. It does not provide the resource usage insights required for this scenario.
- E. Incorrect.
vSphere DRS Recommendations provide guidance on workload placement and balancing within a cluster but are not designed for detailed resource usage or performance monitoring.
